As the leading China 3D sand printer manufacturer, FHZL stands out with stable quality, competitive price and premium service. FHZL 3D sand printing machine, with its intelligent performance and comprehensive functionality, is the best choice for foundries to catch up with Industry 4.0. Patternmaking is the traditional method for metal casting. Patterns are time-consuming and costly, especially for large castings. Besides, patterns are also wasteful and require increasing amounts of storage space. And as 3D printing for sand casting molds becomes more widespread, they are becoming increasingly obsolete.   The conventional sand casting process starts with making the pattern for the final cast, which further will be used for making cope and drag. A taper, or draft angle, is required on the pattern to reduce the damage to the edges while removing the pattern. This draft increases the pattern's surface area and volume, which contributes to extra metal needed to fill the c…
